I put together a list of the NFL's top 20 unrestricted free agents. Maybe it was a waste of time. It'd be interesting to see a few of these guys play for the Chargers, but unless Roger Goodell grants the Bolts a cap exception for our spectacular climate, it's likely not happening. The Chargers probably will check on a few guys on this list, notably guard Andy Levitre. We'll see what comes of it. Twenty isn't a big number. The Chargers will look at dozens of other free agents, including several blockers and defensive backs. The swap meet will be open for several months.

You'll note that four right tackles cracked this list. Just a hunch, but if the Chargers don't sign any of them, I think the ever-vocal Jeromey Clary Fan Club will weigh in.

1 – Mike Wallace, wide receiver

Age: 26

Six-foot, 200-pounder can run by any defender. Has 32 TDs and 17.2-yard catch average in four seasons. A high-risk, high-reward, high-maintenance player who faded after Steelers withheld fat offer. Dolphins look like a match.

Chargers?: They have greater needs elsewhere.

2 – Cliff Avril, defensive end

Age: 26.

Long-armed worker (6-3, 265) gets upfield or powers inside. Had 20.5 sacks in last 32 games with Lions. Is much stronger than when he was drafted (third round, 2008, Purdue). Lions rotated eight linemen in 4-3 defense, aiding his legs.

Chargers?: Their 3-4 isn’t a fit; could suit Browns’ hybrid 3-4.

3 – Andre Smith, right tackle

Age: 26

Is happy Bengals gave franchise tag to end Michael Johnson. Light feet, long arms and huge frame (6-4, 340) make ex-Bama left tackle a top five right tackle—when fit and focused. Fourth-year player is coming off first strong season. Has gained too much weight in years past.

Chargers?: Would be their best blocker.

4 -- Sebastian Vollmer, right tackle

Age: 28.

Consistent protector for Tom Brady. Twice named second-team All-Pro, the German-born Vollmer (6-8, 315) began his college career (Houston) as a tight end. Started 15 games last year. Was limited to five starts in ’11 by back injury.

Chargers?: May have to overpay to get him from Pats.

5 – Greg Jennings, wide receiver

Age: 29

Beset by injuries, played in just 18 games the last two seasons. Looked less brave than in glory years. A true No. 1, though, who can nail all the routes. Was a playmaking star for Super Bowl-winning Packers three years ago. May entice the Texans.

Chargers?: Too risky and too expensive for them.

6 – Dannell Ellerbe, linebacker

Age: 27

Went undrafted out of Georgia. In time, the Ravens, reclamation masters, developed him into a 3-4 inside starter who helped them win the recent Super Bowl. Reaching Colin Kaepernick 1.6 seconds after the snap, Ellerbee (6-1, 236) influenced the controversial pass to Michael Crabtree.

Chargers?: Tough get; the Ravens view him as Ray Lewis' successor.

7 – Wes Welker, slot receiver

Age: 31

The NFL’s top pass-catcher (672) over the last six years, he may be more valuable to the Patriots than any other team because of fit with their system and Tom Brady. Gets open at will but has taken a high number of brutal hits, and drops are on the rise.
